1.首先去info.plist 設置：
2.代碼
NSURL *url = [NSURL URLWithString:@"App-Prefs:root=TOUCHID_PASSCODE"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
[[UIApplication sharedApplication] openURL:url];
}
其它設置界面同理，url換成對應系統界面的參數 即可。
3.touch id 代碼示例
- (void)touchID {
LAContext *context = [[LAContext alloc]init];
NSError *error = nil;
if ([context canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error]) {
[context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
localizedReason:@"為了保證數據安全性，必須開啟指紋認證才能使用，謝謝！"
reply:^(BOOL success, NSError *error) {
if (error) {
NSLog(@"操作失敗");
}
if (success) {
NSLog(@"驗證成功");
} else {
NSLog(@"驗證失敗");
}
}];
} else {
NSLog(@"TouchID設備不可用");
}
}
